spot diameter meaning in Hindi

Examples

1. In the 1970 patent, the spot diameter was around 10 micrometres.
2. Laser spot diameters on target are typically in the range of 2 to 7 mm.
3. In essence, the important output parameter when treating hair ( and other skin conditions ) is power density-this is a combination of energy, spot diameter and pulse duration.
4. The spot diameter of the target is much larger than that of the laser, which makes it necessary to make many laser shots at different places of the target, to get the statistical average of the substance concentration within the target spot.
5. When the optical spot diameter " D ", for example " D " ~ 10 �m, at the surface of an elastically isotropic and flat sample is much greater than the initially heated depth, one can approximate the acoustic field propagating into the solid by a one-dimensional problem, provided that one does not work with strain propagation depths that are too large ( ~ " D " ?/ ? = Rayleigh length, where ? is the acoustic wavelength ).
